	Geophysical and geological investigations of graphite occurrences in Vesterålen, Northern Norway, in 2018 and 2019

;Norges geologiske undersøkelse;RAPPORT;NGU-rapport; No.2019.031;212 pages

Abstract:

Several potential graphite occurrences in Vesterålen were selected for follow-up work based on helicopter-borne geophysical data. The purpose for this is to confirm the existence of the graphite and next to briefly evaluate the quality and quantity of the graphite-bearing structures. The goal for the project, which is sponsored by Nordland county administration, is to increase the knowledge of each individual graphite occurrence. By doing so, the interest in graphite prospecting in Northern Norway may increase, effective prospecting can be implemented, and land planning can be developed with appropriate regard for areas with potential for economic graphite.

	The graphite occurrences of northern Norway, a review of geology, geophysics and resources

;ARTIKKEL;Minerals; No.7(10);24 s. pages

Abstract:

Artikkel i Minerals 2020 nr. 7 vol. 10. Abstract: There are three provinces in Northern Norway in which occurrences of graphite are abundant; the Island of Senja, the Vesterålen archipelago, and the Holandsfjorden area. From these provinces, we report graphite resources from 28 occurrences. We use a combination of airborne and ground geophysics to estimate the dimensions of the mineralized areas, and, combined with sampling and analysis of the graphite contents, this gives us inferred resources for almost all the occurrences. The average TC (total carbon) content is 11.6%, and the average size is 9.3 Mt or 0.8 Mt of contained graphite. We demonstrate that the Norwegian graphite occurrences have grades and tonnages of the same order of magnitude as reported elsewhere. The graphite-bearing rocks occur in a sequence that encompasses carbonates, meta-arenites, acid to intermediate pyroxene gneisses, and banded iron formations metamorphosed into the granulite facies. Available radiometric dating shows that the graphite-bearing rocks are predated by Archean gneisses and postdated by Proterozoic intrusions of granitic to intermediate compositions.
